PurposeThis paper aims to take a look at police‐specific factors of stress – police stressors – and to assess the effects of these factors on police officer burnout. The paper also seeks to test the linearity of these effects.Design/methodology/approachThe study focuses on four stressors: defective leadership, role conflicts, threat of violence, and time pressure. As a measure of burnout, Bergen Burnout Indicator 15 is used. The data are cross‐section in nature and come from the Police Personnel Barometer (PPB) conducted in Finland in 2008. The PPB‐survey targeted the entire police administration in Finland. The response rate was 67.2 percent (n=6,871). The current paper uses a sub‐sample of police officers (constable rank) from three functional areas of policing (n=2,821).FindingsControlling for age, gender, education, shift work, tenure and the function of the police officer, the effects of the different stressors on burnout were all statistically significant. Statistically significant and robust nonlinear effects of the stressors on burnout were also found.Originality/valueThe study introduces a new measure of stress to analyze police work. It takes a preliminary look at the reliability and validity of the measure. The study considers linear as well as nonlinear effects of the stressors on burnout and suggests that the effects under scrutiny are essentially nonlinear.
